Here are the Lewis dot formulae for the bond formations in the given compounds: a) NaCl (Sodium Chloride) Sodium (Na) has 1 valence electron, and Chlorine (Cl) has 7 valence electrons. Sodium transfers its electron to chlorine, forming an ionic bond. Na · + · Cl: Na^+ [: Cl:]^- b) CaF₂ (Calcium Fluoride) Calcium (Ca) has 2 valence electrons, and each Fluorine (F) has 7 valence electrons. Calcium transfers one electron to each of the two fluorine atoms, forming ionic bonds. · Ca · + 2 · F: Ca^2+ 2[: F:]^- c) H₂ (Hydrogen molecule) Each Hydrogen (H) atom has 1 valence electron. They share their electrons to form a single covalent bond. H · + · H H : H d) O₂ (Oxygen molecule) Each Oxygen (O) atom has 6 valence electrons. They share two pairs of electrons to form a double covalent bond, and each oxygen atom has two lone pairs. : O · + · O: : O :: O: e) N₂ (Nitrogen molecule) Each Nitrogen (N) atom has 5 valence electrons. They share three pairs of electrons to form a triple covalent bond, and each nitrogen atom has one lone pair. · N · + · N · : N ::: N: f) H₂O (Water molecule) Oxygen (O) has 6 valence electrons, and each Hydrogen (H) has 1 valence electron. Oxygen forms a single covalent bond with each hydrogen atom and has two lone pairs. H · + · O · + · H H : O : H Send me the next one 📸
